Spray Water pH Advisor
Pick one herbicide or build a tank-mix. See the combined target pH window, identify which partner is limiting it, and adjust your water with confidence.

How to use the tool
Tap your herbicides
Pick one or several. For a tank-mix, the tool finds the overlap of all selected herbicides' windows.
See the limiting partner
If your mix narrows the window, the tool tells you which herbicide is pushing each boundary — and why.
Verify before spraying
Use a calibrated pH meter or a colour-indicating surfactant to confirm target before adding herbicide. Always read the label.
Important — this tool is for general information only
Target pH ranges shown are based on herbicide labels, provincial spray water guidelines, and published literature on pesticide application chemistry. This tool is provided for educational and general informational purposes only. It does not constitute a spray recommendation, a label interpretation, or professional advice of any kind.
The herbicide label is the legal document. Always read and follow the label before mixing or applying any pesticide. This tool covers pH compatibility only — it does not address chemical compatibility, registered tank-mix partners, adjuvant requirements, environmental conditions, or application timing. Do not make spray decisions based solely on this tool.
The amount of water conditioner needed to reach target pH depends on your water's alkalinity, not just its current pH. Always verify final tank pH before adding herbicide.
